Modelling and Simulation of Five-Level H-Bridge Multilevel Inverter for Grid Connected System

The design and simulation of a smart grid energy management system addresses current challenges in grid integration by harnessing renewable solar energy and synchronizing inverter output with grid conditions. Solar panels generate variable DC power, which is converted to AC through an inverter equipped with advanced control algorithms that adjust voltage, frequency, and phase in real-time. This system continuously monitors grid demand and responds to fluctuations by dynamically modulating the inverter output, ensuring stability during sudden load surges and reducing harmonic distortion. Detailed analysis of transient responses and steady-state performance confirms that matching the inverter output to grid parameters not only minimizes voltage fluctuations but also optimizes overall energy quality. By providing precise power injection and maintaining grid stability, this approach overcomes limitations in traditional energy systems, which are not equipped with this technology, resulting in a more resilient, efficient and sustainable energy distribution network.
